Are There Any Additional Steps I Should Take to Reduce Unwanted Calls?

  • Register with the National Do Not Call Registry: This free service allows you to opt out of receiving unsolicited sales calls. While it doesn't block all unwanted calls, it can reduce the number of legitimate telemarketing calls you receive. (whocalledus.net)

  • Be Cautious with Your Phone Number: Limit sharing your number online and avoid posting it publicly. The fewer places your number is listed, the less likely it is to be added to telemarketing lists.

  • Use Carrier Services: Many carriers offer built-in call-blocking features. For example, AT&T provides Call Protect, which blocks robocalls and alerts you to potential spam. (expressvpn.com)
